    组合角色是一组角色，可在活动或流程中用来减少角色的数量。因此，组合角色适用于为角色（该组合角色涉及这些角色）定义的任务和工作产品。通常在为小型团队设计的流程中使用该构造，在此流程中方法内容的多个标准角色被分配给单个资源。通过使用组合角色，流程可向资源建议使用典型角色集群。<br />
</p>
<p>
    组合角色的一个简单示例是<em><strong>开发者</strong></em>，“开发者”将<em><strong>实施者</strong></em>和<em><strong>测试员</strong></em>角色分组在一起。现在，每次在细分结构中要正常使用角色“实施者”或“测试员”时，都会改为使用“开发者”。因此，如果向流程添加将“实施者”或“测试员”作为主执行者的任务描述符，则此角色将自动替换为组合角色实例“开发者”，“开发者”会链接回到“测试员”或“实施者”（或如果“测试员”和“实施者”同时列为任务执行者，则链接回到“测试员”和“实施者”）。
